Hi Team,
I dismantled most of my engine so as to tap the mounting bolt threads larger diameter and deeper in the base.
I also found one of the main bearing housing bolts was stripped--I tapped them deeper too and fitted longer bolts--I machined an alloy plate to go under the engine for the flywheels to clear the wooden board I mounted the unit to.

Anyway I retimed it as any other automatic inlet valve engine I ever worked on in nearly 40 years of playing with these old jiggers--exhaust valve to close at or as near to TDC as the gearing and valve lash settings will allow.

Thanks for the alloy plug tip as my radial engines had these--just trying to think of something as a fix for anyone without the luxury of owning a lathe like myself.

I also found my flywheel appeared to be wobbly, by re-tightening the pair of opposing grub screws, that affix the flywheels to the crank, I got it to run true with little difficulty.

Hello all
I just had a gander at the Banggood website and they have some interesting stuff. I showed it to Mrs Scotty and apparently she already shops there.
She's never bought me anything from there.
Cheers Scott

You are right I just put 20mm by 1 mm in my engine thanks. On the 2 wires that go to the ignition module under the flywheel do they just plug in to the module because one broke off the connection if not I have to try to find a module.

My understanding that is called a hal sensor? This is what the magnet passes to make it fire the plug. Not sure if the sensor comes apart or not? I would try and take it off engine and try to take apart and solder the wires back to sensor. The blue engine plugs together but the polished engine comes all together as one part. Hope this will help you? Thanks

Does any one know there I can purchase the hal sensor? Some one told that this number would fit but they did not. I ordered them from amazon the number is 20 Pack Hall Effect Sensor Transistor for A3144 A3144E OH3144E

Hi Tim,
when we ordered our (3) engines we ordered an extra sensor as by the videos of them and descriptions of problems and mods needed for better life/performance, other peoples experiences show they can seem to have a short life --YEP, mine failed in short order and the replacement is going well--so far, touch wood.
It seems the extra we ordered seems/looks to be slightly different to the original fitment from the factory--likely an upgraded version.

Tim, go to S/S Machine & Engineering ; check out Roy Sholl hall senors. You can talk with him 419-452-6042. Supper nice person to talk too. His units are supper good and you can unplug and replace any part. Sure better than the Chinese units and have the flashing timing light made on them. Please let me know if I can be of any help.

I was talking to a person who builds ignitions and he told me to test the voltages of the 2 wires that go to the sensor under the flywheel. One of the wires had no voltage and the other wire had 4 volts. The wire that had no voltage had no continuity to ground. When I touched both wires together I got a spark from the spark plug wire. He also told me that a hall sensor will not work because it needs 3 wires to operate and there was only 2 wires going to the old switch that was by the magnet. He thinks they are using a reed switch connected to the 2 wires so I orded a few from Mouser part number
Mouser #:
934-MACD-14-10-30. I have to make some kind of holder but I will post my resolts after I et the swic

Hi Tim,
both my pickups--that is the failed unit and the updated one in use-- have 3 wires that are colored thus:- White, Black and Red from the top, when the circuit board is mounted on the engine--this sets the black pickup blob, soldered at the back of the circuit board, facing out to the magnet--wires are facing outwards also ???
